'Supernovae in galaxy clusters with the Multi-Epoch Nearby Cluster Survey'

I will discuss the Multi-Epoch Nearby Cluster Survey (MENeaCS), a long
term program aimed at characterizing the supernova properties in low
redshift galaxy clusters. MENeaCS has discovered 23 cluster SN Ia and
7 core collapse SNe in the 58 X-ray selected galaxy clusters (0.05 < z
< 0.15) surveyed. Four of our SN Ia events have no host galaxy on
close inspection, and are likely intracluster SNe. I will present
results on three topics: the intracluster stellar mass fraction in
clusters, the environmental dependence of the SN Ia rate, and the use
of SN Ia in galaxy clusters to constrain the progenitor of Type Ia
SNe.
